"Perception-based architecture for contemporary health care design" is how the architects from Graft in Berlin describe their work. The statement sounds more than promising: a healing environment based on good design and observing the principles of perception. Following a three-year period of research two pioneering intensive care units (ICUs) were developed at the Charite Hospital in Berlin, Germany and used by four patients. Lighting was to play a key role in the design of the ICUs, given that we all know from relevant studies that the time required for convalescence can be reduced substantially if the patient is exposed to sunlight.
